Description

Technical Field

[0001] This application relates to the technical field of pipeline fixing brackets, and particularly to a fixing structure for cutting anti-corrosion and heat-insulating pipelines. Background Art

[0002] Anti-corrosion and heat-insulating pipe fittings are composed of a high-density polyethylene outer sleeve, a polyurethane foam heat-insulating layer and an inner working pipe body tightly combined together, and are a kind of pipeline material with anti-corrosion and heat-insulating functions. It is widely used in different fields, including industries such as petroleum, chemical industry, pharmacy, food, metallurgy, heat supply, etc.

[0003] When heat-insulating pipes are produced, most of them are produced according to the unified standard dimensions required by customers. However, in specific use, there will inevitably be shortages in length. Therefore, cutting is required. When the existing heat-insulating pipelines are segmented and sheared, most of them are to lift the heat-insulating pipes and then clamp and fix the two ends of the pipeline by means of threaded rods. However, this clamping method is prone to loosening, and after loosening, it is necessary to adjust the threaded rods one by one, which is rather troublesome.

[0004] Therefore, this application provides a fixing structure for cutting anti-corrosion and heat-insulating pipelines, making the clamping and tightness adjustment of the pipeline more convenient. Utility Model Content

[0005] The purpose of this application is to solve the problems existing in the prior art, and to propose a fixing structure for cutting anti-corrosion and heat-insulating pipelines.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0007] A fixing structure for cutting anti-corrosion and heat-insulating pipelines, including a bottom frame, a plurality of brackets are arranged on the bottom frame at intervals, hoop rings are symmetrically arranged on the upper edge sides of each bracket, the ends of all hoop rings are connected together with a pressing plate after winding around the edge side of the bottom frame, the pressing plate is threadedly connected with a screw rod, the screw rod is rotatably installed at the bottom end of the bottom frame, and the screw rod is driven by a driving member to rotate forward / backward.

[0008] Preferably, the bottom frame includes two groups of arch bridges, two connecting columns are vertically arranged at intervals on both sides between the two groups of arch bridges, the brackets are fixed on the two upper connecting columns, a sunken bridge corresponding to each bracket is commonly fixed on the two lower connecting columns, and the upper and lower ends of the screw rod are respectively rotatably installed on the sunken bridge and the bottom end of the bracket.

[0009] Preferably, sleeve rings are welded and fixed at both ends of the hoop ring, and sleeve frames matched with the sleeve rings are arranged on the pressing plate and the bracket.

[0010] Preferably, the bracket includes a mounting seat, the mounting seat is inserted on the two upper connecting columns, rib plates are symmetrically fixed at the upper end of the mounting seat, and an arc-shaped placement plate is commonly fixed at the upper ends of the two rib plates.

[0011] Preferably, the inner wall of the placement plate is a triangular sunken groove.

[0012] Preferably, the driving member includes a worm rotatably mounted on the chassis, a wheel disc is provided at the end of the worm, the worm meshes with a worm gear, and the worm gear is fixed to the end of the screw rod.

[0013] Compared with the prior art, the present application provides a fixing structure for cutting an anti-corrosion and heat-insulating pipe, and has the following beneficial effects:

[0014] 1. During use, the heat-insulating pipe is passed through all the hoop rings and placed on the bracket, and then the screw rod is driven to rotate forward by the driving member. The forward rotation of the screw rod drives the pressing plate to descend, and the descent of the pressing plate drives the ends of all the hoop rings to sink and constrict, thereby tightly fixing the heat-insulating pipe and keeping the heat-insulating pipe stable on the bracket. When the fixing of the heat-insulating pipe becomes loose due to cutting vibration, the screw rod is continuously driven to rotate forward by the driving member, so that the pressing plate descends, thereby playing a role in tensioning. According to the above structure, for the clamping and fixing as well as the loosening and tensioning of the heat-insulating pipe, only by controlling the lifting of the pressing plate through the screw rod can the synchronous tensioning and loosening of all the hoop rings be controlled. The operation is convenient and simple, and there is no need to adjust one by one, saving manpower.

[0015] 2. In this solution, the hoop ring fastening can be applied to the fastening and fixing of heat-insulating pipes with different diameters, greatly improving the practicability.

[0016] Other advantages, objectives and features of the present application will be described to some extent in the subsequent description; and to some extent, based on the study of the following text, it will be obvious to those skilled in the art; or, it can be taught from the practice of the present application.

Specific implementation manner

[0024] Next, in combination with the drawings in the embodiments of the present application Figures 1-6 , the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0025] Embodiment 1. To solve the problems existing in the prior art, this embodiment provides a fixing structure for cutting an anti-corrosion and heat-insulating pipeline, including a chassis 1. A plurality of brackets 2 are arranged at intervals on the chassis 1. Hoops 3 are symmetrically arranged on the side edges of the upper ends of each bracket 2. The ends of all the hoops 3 are wound around the side of the chassis 1 and then commonly connected to a pressing plate 4. The pressing plate 4 is threadedly connected to a screw 5. The screw 5 is rotatably installed at the bottom end of the chassis 1 and is driven by a driving member to rotate forward / backward.

[0026] Principle details of this embodiment:

[0027] A fixing structure for cutting an anti-corrosion and heat-insulating pipeline includes a chassis 1. A plurality of brackets 2 are arranged at intervals on the chassis 1. The inner circle of the bracket 2 is arc-shaped for placing and supporting the pipeline. And on one side end of each bracket 2, there are convex edges symmetrically arranged in the placing direction of the bracket 2. A hoop 3 is installed on each convex edge. The hoop 3 is made of a flexible metal, such as aluminum alloy. The ends of all the hoops 3 are wound around the side of the chassis 1 and then commonly connected to a pressing plate 4. A plurality of guide posts are arranged on the lower end surface of the chassis 1. The pressing plate 4 is provided with guide holes corresponding to the guide posts one by one, so that the pressing plate 4 can slide along the guide posts, and then the pressing plate 4 can slide vertically relative to the chassis 1. The pressing plate 4 is threadedly connected to a screw 5. The screw 5 is rotatably installed at the bottom end of the chassis 1 and is driven by a driving member to rotate forward / backward.

[0028] According to the above technical solution:

[0029] During use, the heat-insulating pipe is placed on the bracket 2 after passing through all the hoops 3, and then the screw 5 is driven to rotate forward by the driving member. The forward rotation of the screw 5 drives the pressing plate 4 to descend, and the descent of the pressing plate 4 drives the ends of all the hoops 3 to sink and constrict, thereby tightly fixing the heat-insulating pipe and keeping the heat-insulating pipe stable on the bracket 2. After cutting is completed, the screw 5 is driven to rotate backward by the driving member to drive the pressing plate 4 to rise, and the hoop 3 is loosened. At this time, the heat-insulating pipe can be moved.

[0030] During the cutting process, when the fixation of the heat-insulating pipe becomes loose due to cutting vibration, the screw 5 is continuously driven to rotate forward by the driving member, so that the pressing plate 4 descends, thereby playing a role in tensioning.

[0031] According to the above structure, for the clamping and tightening as well as the loosening and tensioning of the insulation pipe, only by controlling the lifting of the pressing plate 4 through the screw rod 5 can the synchronous tensioning and loosening of all the hoop rings 3 be controlled. The operation is convenient and simple, and there is no need to adjust one by one, saving manpower.

[0032] Moreover, in this solution, the fastening of the hoop ring 3 can be applied to the fastening and fixing of insulation pipes with different diameters, greatly improving the practicability.

[0033] In this embodiment, a friction layer is provided on the inner wall of the side where the hoop ring 3 contacts the insulation pipe, which is used to increase friction and enhance the braking ability for the insulation pipe.

[0034] Embodiment 2, in a further embodiment of this solution, a light and simple chassis 1 structure is provided in this embodiment:

[0035] The chassis 1 includes two groups of arch bridges 101 as the support structure. On both sides between the two groups of arch bridges 101, two connecting columns 102 are vertically arranged at intervals, forming the installation and connection components. The bracket 2 is fixed on the two upper connecting columns 102 to realize the installation and fixation of the bracket 2. A sunken bridge 103 corresponding to the bracket 2 is jointly fixed on the two lower connecting columns 102, and the upper and lower ends of the screw rod 5 are respectively rotatably installed on the sunken bridge 103 and the bottom end of the bracket 2, providing an installation basis for the screw rod 5.

[0036] Compared with the traditional table-frame type clamping equipment, the structure of the chassis 1 in this embodiment is simpler and lighter, minimizing the use of production materials and reducing the production cost.

[0037] Embodiment 3, in a further embodiment of this solution, sleeves are welded and fixed at both ends of the hoop ring 3, and sleeve brackets 9 matched with the sleeves are provided on the pressing plate 4 and the bracket 2. This enables the two installation parts of the hoop ring 3 to deflect flexibly, avoiding breakage due to long-term hard stress pulling.

[0038] Embodiment 4, in a further embodiment of this solution, a bracket 2 structure adapted to the chassis 1 in this solution is provided:

[0039] The bracket 2 includes a mounting seat 201. Two jacks are symmetrically arranged on the mounting seat 201, and the two upper connecting columns 102 pass through the two jacks to realize the installation of the mounting seat 201 on the chassis 1. The mounting seat 201 and the upper connecting column 102 are fastened and connected by countersunk head screws, thereby realizing the fixation of the mounting seat 201 on the chassis 1. This provides an installation basis for the bracket 2.

[0040] On the upper end of the mounting base 201, rib plates 202 are symmetrically fixed. The two rib plates 202 are respectively located above the two upper connecting columns 102. The upper ends of the two rib plates 202 incline towards the center line of the chassis 1. The upper ends of the two rib plates 202 are jointly fixed with an arc-shaped placement plate 203. The placement plate 203 is used to place the heat preservation pipe. The two rib plates 202 provide an installation foundation for the placement plate 203. And the rib plates 202 are inclined towards the center of the chassis 1, which also facilitates dispersing the load from the heat preservation pipe on the mounting base 201. At the same time, the supporting force is towards the center line, which can also play a role in preventing shaking.

[0041] Embodiment 5, in a further embodiment of the present solution, the inner wall of the placement plate 203 is a triangular sunk groove. Compared with the arc-shaped inner wall, the triangular sunk groove has a greater limitation on the cylindrical heat preservation pipe. It is not only applicable to heat preservation pipes of different calibers, but also limits both sides of the heat preservation pipe through the side walls of the triangular sunk groove. Coupled with the hoop 3, three-point fastening is formed to realize the fixation of the heat preservation pipe, and it is more reliable.

[0042] Embodiment 6, in a further embodiment of the present solution, the driving member includes a worm 7 rotatably installed on the chassis 1. A wheel disc 8 is provided at the end of the worm 7. The worm 7 meshes with a worm gear 6, and the worm gear 6 is fixed to the end of the screw rod 5. The screw rod 5 is driven to rotate through the worm gear 6 and the worm 7. The braking property of the worm gear 6 and worm 7 structure is used to limit the screw rod 5, preventing the screw rod 5 from deflecting due to shaking during the cutting process, so that the hoop 3 becomes loose.

Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution of the present application and its application concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
